SPECIFICATION forming part of Letters Patent No. 783,195, dated February21, 1905.

Application filed April 3, 1903. Serial No. 150,976.

To n.17/ whom t may concern:

Be it known that we, WILLIAM B. HARRISON and JOSEPH H. DIEL, citizens ofthe United States, residing at Stockton, in the county of San Joaquinand State of California, have invented certain new and usefulImprovements in Storage-Elevators, of which the following is aspecification.

This invention is an apparatus for facilitating the piling and stackingof merchandise and the lifting of the same from one level to another. Ithas therefore a somewhat comprehensive range of action; but itsessential principles are embodied and are herein described and shown asapplied to a machine for stacking and piling bags filled with grain.Obviously, however, a machine embodying the principles herein described,and shown in the drawings, can be used in other relations and for otherpurposes.

In the drawings in which the present machine is illustrated, Figure 1 isa front elevation of the machine. Fig. 2 is a side eleva- Fig. 3 is atop plan.

In describing the apparatus we shall consider it as a device for pilingor stacking grainbags in a warehouse in which they are to be stored. Inthis connection the idea is to save a great deal of labor and toeconomize in the work by providing a portable machine which willaccomplish what at present requires a number of men. We provide aportable apparatus containing a lifting device and under the control ofan operator and which is of suficient height to lift the sacks of grainor other merchandise to a suitableposition for discharging them at thepoint where they are to be stacked or piled. The machine is mounted uponcasters or rollers, so that it can be moved from place to place. Anynumber of such machines can be used in the warehouse or other situationwhere the merchandise is to be lifted and stored.

In the drawings, l represents a frame of any suitable height supportedupon rollers or casters 2, so that it can be moved from place to place.The front beams of the frame are preferably slightly inclined, as shownin Fig.

2. These front beams 3 and 4 on both sides are supported so as to formguideways for a carriage or elevator 5, which is movable bodily in saidguides from the bottom toward the top and back again. The carriage 5 isprovided with guide-rollers 6, and these rollers are mounted upon anaxle or shaft 7.

vThe normal position of the device is best indicated by Fig. 2, in whichthe carriage is shown as at the bottom of the machine, ready to receivea number of grain-bags or other merchandise to be lifted or discharged.

The carriage is pivoted upon the shaft 7 and is provided with a hook 8,so that when said carriage arrives at a certain point the hook will beengaged by a mechanism to be hereinafter described, and this engagementwill cause the entire carriage to tilt and discharge its load in itselevated position. It must beunderstood that the carriage, as shown inFig. 2, is practically at the level of the floor, so that the grain-bagsor other' merchandise can be easily dumped into or upon it.

Adjustably supported in the machine is a table 9, upon which is mounteda chute I0. The purpose of this table and of its vertical adjustment isto enable the carriage or elevator which conveys the material upwardlyto discharge it at the proper height. In stacking grain-bags, forinstance, after they have been piled as high as can be conveniently doneby hand this apparatus is brought into use and the table 9, with itschute 10, is adjusted to the elevation at which the next load should bedelivered. Consequently as the pile grows in height the table 9, withits chute, is adjusted vertically higher and higher. The hook 8 on thecarriage 5 strikes a bail 11 on the table 9, and as its upward movementcontinues it is caused to turn upon its axis 7, and so discharge itscontents into the chute l0. The dotted line .fr in Fig. 2 indicates thecourse of the carriage in turning so as to register with the chute. Itwill have been evident from this description that after the grain-bagsor other merchandise have been piled to a certain height the table 9 andits chute can be adjusted to that height, and one or more men standingon the pile or stack can riage or the table can be moved under thereceive the additional merchandise as fast as l it is lifted by thecarriage and discharged into the chute.

The construction and Varrangement of the bail 11 is best shown in Fig.3. Itis pivoted in the table 9, and one end is provided with acounterweight 12 for restoring it to normal position. This manner ofpivoting the bail enables the hook 8 of the carriage to lift said bailas the carriage moves upwardly. When the carriage movesA downwardly, thecounterweight attached to the bail automatically restores the latter tothe position of Fig. 2.

Operating means are provided for accomplishing the various motions ofthe carriage and of the adjustable table, and in the draw'- ings we haveshown such operating means, although they are not the only operatingmeans which are adapted to accomplish the same results. In the presentcase we have conventionally shown an electric motor 13 supplied withelectrical power in any suitable way and whose shaft 14 is geared downto a pulley 15, secured to the shaft 16. Upon this shaft 16 is carriedthe pinion 17, which engages with the gears 18 19 and drives themcontinuously. These gears are mounted upon shafts 21 22, respectively,which carry drums 23 24, the latter receiving the cable or belting whichaccomplishes the adjustment of both the carriage and the table. On thedrum 24 is wound a cable 25, which extends up and over a pulley 26 andthence down to the axis of the carriage. Acable 27 is attached to drum23, being wound one or more times around said drum, passing thence upand over a pulley 24X at the top of the frame, thence down to the table9, where it is attached by a clamp, thence passing under a guide-pulley27EL on the frame, thence lone or more times around drum 23, thencepassing up and over an upper pulley numbered 24, thence down to table 9,passing through a hole in rear of table, thence to the opposite side oftable, the direction of the cable being applied to the drums and pulleyson the opposite side to correspond with above description. The cable onboth sides of the table is one continuous cable.

It being understood that the gears carried by the shafts 21 22 rotateconstantly and that one shaft and gear controls the carriage, while theother shaft and gear controls the table, means have been provided forengaging these gears independently and separately with thecable-carrying drums, so that either the carcontrol of the operator. Forthis purpose any ordinary clutch can be provided, such as the slidingclutches 28 29, which by means of the levers 31 32 can be caused tobring either shaft 21 or 22 and the appropriate drums carried by theminto operation.

It will be understood that the pinion 17 and the gears 18 and 19 areconstantly revolving,

but that the shafts upon which these parts are mounted are normallystationary.V The op- -erator by means of the levers 31 and 32 can causethe carriage to travel upwardly in .its guides, bearing its load ofmerchandise, which merchandise will be discharged into the chute 10 bythe hook and bail before described. Also under control of the sameoperator is the handle 32, by means of which the table 9, which carriesthe chute 10, can be elevated to the proper point so that the workmen ontop of the pile will always receive the merchandise at the properheight.The idea is that a discharge-chute shall be provided which is adjustableas to height and which discharges material which is elevated by means ofa carrier having an automatic tilting device for causing such discharge.

We do not limit ourselves to the particular constructions or devicesshown in the accompanying drawings and herein described, as other meansfor elevating and adjusting' the carriage and table might be employed,and we desire to avail ourselves of all modifications and equivalentswhich fall properly within the spirit of our invention. For instance,the carriage might be made long enough to form in itself the chute andto discharge the merchandise elevated by it.

On each of shafts 21 and 22 a frictional drum a a is attached, Fig. 1. Asteel or iron strap 6X is attached at rear of frame, thence around drumon shaft 21 one or more times, thence down to a lever C, attached to theframe, forming a friction-brake, which brake is for the purpose ofholding in position frame 9 and carriage 5. The strap belonging to druma is marked ax. i

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is@
